What Are Google Ads Keywords and How Do They Work?

Choose keyword themes around business priorities

Google Ads keywords are words or phrases used in Search campaigns to help match adverts with relevant searches. They describe the demand you want to reach, but do not determine every query word for word. Match types, exclusions and campaign settings influence eligibility, while actual search terms reveal how targeting is working in practice.

A useful keyword list reflects the products or services the business wants to sell and the customers it can serve. Search volume alone cannot tell you whether the demand is commercially worthwhile. Begin with the offer, geography and enquiry you want before researching phrases.

At Colne Digital, we first discuss the client’s business, products and goals. We then research the client’s website and competitor websites to develop relevant themes. Our Google Ads management approach continues that assessment after launch using search and outcome data.

The difference between keywords and search terms

Our beginner’s guide to Google Ads explains how advertising fits together. A keyword is a targeting input in the advertising account. A search term is what someone types into the search engine. One keyword can match several different queries, depending on the match type and other settings.

For illustration, a keyword theme around boiler repair could attract searches about an urgent repair, typical prices or a particular supplier. Those people may have different needs. The fact that each search mentions a boiler does not mean each person wants the same service.

Google’s search terms report helps show how queries relate to account keywords. It omits some low-activity queries for privacy, so the visible report is useful evidence rather than a complete record of every search.

How the three keyword match types work

Broad match can reach searches related to the keyword, including searches that do not contain its direct meaning. It gives wider reach and needs suitable conversion measurement and bidding oversight. Wider eligibility does not guarantee better or worse customers by itself.

Phrase match can reach searches that include the meaning of the keyword. Exact match can reach searches with the same meaning or intent. Exact therefore does not mean only the identical characters you typed into the account.

Google’s keyword matching guidance explains these distinctions. Use match types to manage the scope of a test, then review real searches and outcomes. Treating phrase match as a fixed word-order rule would misrepresent how positive matching works today.

Match type is only one part of relevance

Geography, the advert and the landing page also influence the customer journey. A carefully chosen keyword can still send someone to a page that does not answer their need. A relevant enquiry can also be lost if the contact route fails.

Judge the chain from query to customer action. If the words look appropriate but the results do not, check where the mismatch occurs before expanding the keyword list.

Build the starting list from genuine services

First agree the priority products or services, the locations the business can fulfil and the outcomes it values. Ask about work it does not want, brands it does not supply and any commercial constraints. An urgent repair and a planned installation may deserve different messages and pages.

Next, use website research and market evidence to identify how customers describe those needs. Competitor websites can reveal service language and offer structures, but they do not prove which keywords are profitable in a competitor’s account.

Group closely related themes so the advert and destination can answer a clear need. Keep the initial structure manageable enough to learn from. There is no universal correct number of keywords for every business.

Choose intent rather than chasing volume

Intent is the purpose behind the search. Someone seeking a quote may be closer to contacting a provider than someone researching a technical definition. However, research searches are not automatically worthless: some businesses need to reach people before they request prices.

Decide which stages the campaign should support and what you can afford to test. A small local service budget may justify a tighter initial focus than a business with a longer sales cycle and more resources.

Use the advert to clarify the service and the page to answer the next question. A specific keyword should not promise something the business cannot deliver. Our Google Ads cost guide explains why budgets need to reflect the market and likely customer value.

An Essex plumbing account example

Before working with Colne Digital, a service business in Essex had spent substantial time and money targeting competitor searches. The business was a plumber seeking suitable customer demand.

When we examined the data and tracked outcomes, a large proportion of that competitor traffic related to existing customers seeking the named businesses. They were looking to report service issues or faults under warranty, rather than choosing a new plumber.

The searches sounded commercially relevant because they named plumbing businesses. The underlying need was often aftercare from an existing provider. This showed why enquiry context matters when judging a keyword theme.

That observation does not establish that all competitor campaigns are ineffective. People comparing suppliers can behave differently from people seeking support. Nor do we claim a quantified improvement from this example; its value is the finding about intent.

Use negatives to remove unsuitable demand

Negative keywords restrict searches you do not want to reach. They can help address confirmed mismatches such as unsupported services or inappropriate competitor support demand. Choose the scope and negative match type carefully so you do not exclude useful queries.

Positive and negative match types work differently. A negative is not simply a targeting keyword with its effect reversed. Before excluding an ambiguous theme, confirm the service boundary and desired customer journey with the client.

At Colne Digital, exclusions are discussed and reviewed throughout the relationship. A business may add a service or change priorities, making an old restriction inappropriate. Keep a reason for meaningful exclusions so later reviews can revisit them.

Assess results after launch

Review available queries alongside spend and tracked outcomes. Ask whether the enquiries fit the service, location and customer type you intended to reach. A high click-through rate can show interest without proving that the demand is profitable.

Allow enough evidence to develop while correcting clear mistakes. New or changed campaigns may need time to settle, but a learning period should not prevent action on obviously unsuitable traffic or broken measurement. Record important changes so the next comparison remains interpretable.

Expand promising themes when the evidence and budget support it. If results are weak, investigate the offer, advert, page and conversion definitions as well as the keyword. Adding more phrases is not a complete optimisation strategy.

Keywords across other Google Ads formats

This guide focuses on targeting keywords in standard Search campaigns. Other formats use different inputs. Shopping relies heavily on product information, while Performance Max combines broader signals and supplied material across channels. Its search themes are not a conventional Search keyword list.

Choose the campaign type around the customer journey. If you need help deciding how tightly to start, our Google Ads audit can support a discussion about the current account, priorities and available evidence.
